Much like the latest Fire TV Stick update, the new Amazon Fire TV software update, version 18.104.22.168_user_514015320, that is currently rolling out to devices makes no visible changes to the Fire TV. I initially speculated that this new update would bring the promised HBO search integration, but it turns out a software update is no longer required to add additional search sources. Fire TVs running the previous software version are also getting HBO results within voice and text searches.
This wasn’t always the case. When Amazon added Crackle and Showtime search integration with the 22.214.171.124 update, the previous software version distinclty lacked the new search sources. At some point since 126.96.36.199, Amazon must have added in the ability to update search sources dynamically without the need of a full software update. All indication is that this Fire TV update and its sister Fire TV Stick update seem to only make changes behind the scenes.
Amazon has officially listed the features of this update to be “Bug Fixes” and nothing else.
